Koyata Iwasaki was the eldest son of Yanosuke Iwasaki, the second president of Mitsubishi (when the company was still a unified entity). After enrolling at the University of Tokyo, Iwasaki travelled to the United Kingdom to study at the University of Cambridge. He completed the course and then returned to Japan in 1906. In May that year, he became Mitsubishi’s deputy president. In that role, Iwasaki made notable contributions to cultural life, such as founding Seikei Academy (which became Seikei University) and Tokyo Philharmonic Society. In 1916, he became president of the company. During the 1930s, he codified Mitsubishi’s three corporate principles.

Mitsubishi Yowakai Foundation traces its origin to Mitsubishi Club (Mitsubishi Kurabu) , an organization established within Mitsubishi in September 1914.
Led by Hisaya Iwasaki, the third president of Mitsubishi (then a unified company), with Koyata Iwasaki, Mitsubishi’s deputy president, acting as deputy, Mitsubishi Club was founded to promote fraternity and fitness among Mitsubishi employees. Rather than just providing a form of employee benefits for employees, the club management sought to promote employees’ personal and moral development.

Koyata Iwasaki Founds
Mitsubishi Yowakai Foundation

In November 1940, Mitsubishi president, Koyata Iwasaki, spun off Mitsubishi Club into Mitsubishi Yowakai Foundation (Mitsubishi Yōwakai) and became the foundation’s first chairman.
The foundation released a publication describing its genesis, On the Foundation of Mitsubishi Yowakai Foundation (Mitsubishi Yōwakai setsuritsu ni saishite), and another outlining its founding ethos, The Credo of Mitsubishi Yowakai Foundation (Mitsubishi Yōwakai kyōjō). Regarding the foundation’s name, Yowakai means “yowa-association.” The word “yowa” (養和), meaning “nourish harmony,” was coined by Koyata Iwasaki. This expression was inspired by a passage from the Biography of Zhou Pan (in the Later Book of Han): 神嗇和養,不以榮利滑其生術 “[Fang Hui and Qi Fu] cherished the gods and nourished harmony.
Never did they allow vanities to jeopardize their method for living prosperously.” Iwasaki interpreted this to mean that people should direct their attention away from trivialities and toward the cultivation of moral fortitude, and that people should devote their heart and soul to fostering harmony with others instead of focusing only on personal interest and success. Another inspiration came from an article of the Seventeen-Article Constitution, attributed to Prince Shōtoku. The article reads: “Harmony shall be treasured and conflict shall be avoided.” The commonality between the two sources is that they both emphasize the value of harmony.
Iwasaki believed that businesses should serve the national interest and that the fate of a business depends on its people. On that basis, he held that a business would prosper if it cultivates strength of character in its employees. It was upon these values that Mitsubishi Yowakai Foundation was founded.

Nourishing and treasuring harmony constitutes the traditional ethos of Mitsubishi employees.
It remains our firm belief, since the time of our foundation, that although a business be divided into parts and an organization be divided into divisions, all employees should cooperate with one another in a spirit of harmony and fraternity, devoting their energies toward the interest of the company as a whole, and in so doing serve the national interest and the common good.
Upon this tenet, our predecessor company, Mitsubishi, had long provided facilities in diverse locations for promoting fraternal relations among employees there. In September 1914, Mitsubishi, in view of the developments around the world at that time, decided to fortify its infrastructure and to unify its social facilities, which until then had been managed separately by regional offices or by local mining and shipyard departments and so forth. Accordingly, Mitsubishi founded Mitsubishi Club to provide unified management of these facilities.
Mitsubishi Club was established in Mitsubishi’s corporate headquarters with a branch office in each major city.
Mitsubishi Club’s activities included publishing a journal, holding seminars, promoting sport and exercise, and providing recreational dormitories offering rest and recuperation to employees and their family members. These and many other examples beside embodied a common principle: that employees should cultivate a sound body and mind, that harmony should prevail among superiors and fraternity among inferiors, and that employees should devote their efforts to serving the greater good.
Now, twenty years’ later, Mitsubishi Club is enriching its activities day by day. We now have 60 branches with more than 90 dormitories and other facilities and more than 20,000 members, compared to the 3,300 members at the time the club was founded. However, considering recent drastic developments in the world, as well as the growth and prosperity of Mitsubishi, we face a need to further expand and fortify our organization.
Accordingly, we decided to discontinue Mitsubishi Club and to run its operations separately from Mitsubishi by incorporating Mitsubishi Yowakai Foundation as an independent organization.
Although I am convinced that Mitsubishi and Mitsubishi Yowakai Foundation share the same unshakeable vision and credos, such a separation was necessary to expand our businesses and further secure our interests.
Our nation’s present circumstances call for unification of the inward and outward and for solidarity between superiors and inferiors.
It is my fervent hope that employees of Mitsubishi will always keep in mind our traditional ethos: to start by nourishing harmony within the company so that you may thenceforth serve your greater purpose as subjects of Yamato, ever united in loyalty.

The Credo of
Mitsubishi Yowakai Foundation
(Mitsubishi Yōwakai kyōjō)

Know that each and every day is to be treasured and that life is a dojo for self-cultivation.

Reading is not just for pleasure but for expanding your horizons and cultivating a clear mind.

It is good to enjoy in pastimes such as Go, poetry, and singing, and to indulge in nostalgia at appropriate times

It is most desirable to train your body and mind through the martial arts, and all the more so if, in so doing, you master the art of working together with colleagues.

We are as one with others if we share the same ideals; let us therefore embody the ethos of Yowa (nourishing harmony) and commit ourselves in service, together with others, toward the greater good.

Promoting Sport

In 1969, a year that marked Mitsubishi’s centenary, the corporation made promotion of sport in the community an integral part of its business. In April 1974, Mitsubishi Yowakai Foundation opened a boathouse in Toda, Saitama. In 1975, it opened a sports center in Sugamo, Tokyo.
The Sugamo sports center was refurbished in 1994, and the revamped center was opened in October of the following year. In May 2003, the center opened the Shiseikan dojo.
In October of the same year, the foundation opened a sports ground in Chofu. Today, the foundation runs sports facilities in Sugamo (Tokyo), Chofu (Tokyo), and Toda (Saitama) as part of two undertakings. The first undertaking is to promote sport, fitness, and wellbeing among members of the community of all ages. The second is to manage sports facilities for the benefit of club members.
In April 2011, Japan introduced a new legal framework for nonprofit organizations. Under this system, the Tokyo Metropolitan Government officially recognized Mitsubishi Yowakai Foundation as a “public interest corporation” (kōeki zaidan hōjin) whose purpose is to “embody the values of Mitsubishi Yowa by promoting sports, contributing to the public’s mental and physical wellbeing, and cultivating strength of character.”
